## Project:	WBI2C ... a set of (Wishbone controlled) I2C controller(s)
##
## Purpose:	Since the I2C CPU/microcontroller approach requires a set of
##		instructions, we need some software to generate those
##	instructions.  That's the purpose of the I2C microcontroller assembler,
##	or i2casm as it is called here.  The i2casm is found in this directory
##	in the form of Flex script, i2casm.l that needs to be built into an
##	executable.  This makefile coordinates the build of this executable.
